Ingredients

For the Classic Vanilla Butter Cake:

• 1 ½ cups (3 sticks or 340g) unsalted butter, softened to room temperature
• 2 ½ cups (500g) granulated sugar
• 4 large eggs, at room temperature
• 1 tablespoon pure vanilla extract (use good quality!)
• 3 cups (360g) all-purpose flour, sifted
• 1 tablespoon baking powder
• ½ teaspoon salt
• 1 cup (240ml) whole milk, at room temperature
• ½ cup (120ml) buttermilk, at room temperature

For the Buttermilk Sauce:

• 1 cup (240ml) buttermilk
• ½ cup (113g) unsalted butter
• 1 cup (200g) granulated sugar
• 1 teaspoon pure vanilla extract
• ½ teaspoon baking soda

For Garnish:

• Powdered sugar, for dusting

Instructions

For the Classic Vanilla Butter Cake:

1. Preheat your oven to 325°F (160°C). Grease and flour a 9-inch springform cake pan. Line the bottom with parchment paper. Prepare a water bath by placing the springform pan inside a larger roasting pan.
2. In a large bowl, cream together the softened butter and granulated sugar with an electric mixer on medium-high speed until light and fluffy, about 5-7 minutes. Scrape down the sides of the bowl as needed.
3. Add the eggs one at a time, beating well after each addition until fully incorporated. Stir in the vanilla extract.
4. In a separate medium bowl, whisk together the sifted all-purpose flour, baking powder, and salt.
5. In a liquid measuring cup, combine the whole milk and buttermilk.
6. With the mixer on low speed, gradually add the dry ingredients to the wet ingredients in three additions, alternating with the milk mixture in two additions, beginning and ending with the dry ingredients. Mix until just combined after each addition; do not overmix. The batter should be smooth and thick.
7. Pour the cake batter into the prepared springform pan. Smooth the top with a spatula.
8. Carefully place the roasting pan with the cake pan into the preheated oven. Pour hot water into the roasting pan until it comes halfway up the sides of the springform pan.
9. Bake for 70-85 minutes, or until a wooden skewer inserted into the center of the cake comes out clean. The top should be golden brown and spring back when lightly touched.
10. Carefully remove the cake from the water bath and the roasting pan. Let it cool in the springform pan on a wire rack for 15-20 minutes.
11. Run a knife around the edges of the pan before releasing the springform. Invert the cake onto a wire rack, remove the parchment paper, and then flip it back upright to cool completely.

For the Buttermilk Sauce:

1. While the cake is cooling, prepare the buttermilk sauce. In a medium saucepan, combine the buttermilk, butter, and granulated sugar.
2. Heat over medium heat, stirring constantly, until the butter is melted and the sugar is completely dissolved. Bring the mixture to a gentle boil, then remove it from the heat.
3. Stir in the vanilla extract and baking soda. The sauce will foam up slightly due to the baking soda reacting with the buttermilk; this is normal.
4. Let the sauce cool slightly, but serve it warm or at room temperature.

To Serve:

1. Once the cake is completely cool, slice it generously.
2. Drizzle each slice with the warm buttermilk sauce.
3. Dust with powdered sugar just before serving, if desired.

Cooking Tips and Variations

Achieving the perfect Classic Vanilla Butter Cake and its accompanying sauce is all about attention to detail. For the cake, ensure all your dairy ingredients and eggs are at room temperature. This allows them to emulsify properly with the butter and sugar, creating a smoother batter and a finer, more even crumb. Don’t rush the creaming process; whipping the butter and sugar until light and fluffy is crucial for incorporating air, which contributes to the cake’s light texture. When adding the dry and wet ingredients, mix only until just combined to avoid developing the gluten too much, which can lead to a tough cake. Overmixing is the enemy of a tender crumb.

The water bath technique for baking this tall cake is essential. It provides a moist environment in the oven, which prevents the cake from drying out and helps it bake evenly without developing a thick, dark crust. This method is often used for cheesecakes and other delicate cakes to ensure a custardy, tender result. For the buttermilk sauce, make sure to stir constantly as it heats to prevent scorching and ensure the sugar fully dissolves. The baking soda is key for giving the sauce its unique texture and tang, reacting with the buttermilk to create a slight effervescence and richness.

To vary this recipe, consider adding the zest of one lemon or orange to the cake batter along with the vanilla for a brighter flavor profile. You could also swirl in a bit of berry compote to the batter before baking for a fruity twist. For the sauce, a pinch of nutmeg or cardamom could add an interesting depth of flavor. If you find yourself without buttermilk, you can easily make a substitute: for 1 cup of buttermilk, add 1 tablespoon of lemon juice or white vinegar to a liquid measuring cup, then fill the rest with whole milk until it reaches the 1-cup mark. Let it sit for 5-10 minutes until it slightly curdles before using.

Storage and Reheating

This Classic Vanilla Butter Cake with Buttermilk Sauce can be stored at room temperature, covered tightly, for up to 2 days. If you live in a warm or humid climate, or if you want to extend its freshness, it’s best to store it in the refrigerator. In the fridge, the cake will stay fresh for up to 5 days. Make sure to wrap it well in plastic wrap or place it in an airtight container to prevent it from drying out or absorbing other odors from the refrigerator. The buttermilk sauce can be stored separately in an airtight container in the refrigerator for up to a week.

When serving chilled cake, allow slices to come to room temperature for about 30 minutes before enjoying, as this enhances the flavor and texture. If you prefer your cake warm, individual slices can be gently reheated in the microwave for 15-30 seconds until just warm. The buttermilk sauce can also be gently reheated on the stovetop over low heat, stirring frequently, or in the microwave in short bursts, until it reaches your desired warmth. Avoid overheating the sauce, as it can separate or become too thick. For best results, reheat only the amount of sauce you plan to use.

Frequently Asked Questions

What makes this vanilla butter cake “classic”?

A “classic” vanilla butter cake typically refers to a rich, dense yet tender cake made with a generous amount of butter, sugar, eggs, flour, and vanilla. It’s known for its golden color, moist crumb, and prominent vanilla flavor. This recipe adheres to those traditional characteristics while elevating it with the specific inclusion of buttermilk for extra tenderness and the unique buttermilk sauce.

Can I make this cake ahead of time for a special occasion?

Absolutely! The cake itself can be baked one day in advance. Once completely cooled, wrap it tightly in plastic wrap and store it at room temperature. The buttermilk sauce can also be made a day or two ahead and stored in the refrigerator. On the day of serving, simply reheat the sauce gently and assemble the cake by slicing and drizzling.

Why is there buttermilk in both the cake and the sauce?

Buttermilk plays a crucial role in both components. In the cake, its acidity reacts with the baking powder, contributing to a lighter, more tender crumb and a subtle tangy flavor that balances the sweetness. In the sauce, buttermilk provides a creamy texture and a distinctive tangy-sweet profile that beautifully complements the rich butter cake, preventing it from being overly sweet and adding a layer of complex flavor.

What if my buttermilk sauce separates when reheating?

If your buttermilk sauce separates slightly upon reheating, don’t worry! This can sometimes happen, especially if it’s reheated too quickly or at too high a temperature. Simply whisk it vigorously with a fork or a small whisk as it heats, or immediately after removing it from the heat. This should help re-emulsify the ingredients and bring it back to a smooth consistency.
